(LENOX, Mass.) – English comic actor Eddie Izzard and Tony Award-winning vocalist Idina Menzel perform at Tanglewood on Thursday, August 27, and Saturday, August 29, respectively, at 7 p.m. Izzard is known for bizarre, tangential, and absurd comic narratives rooted in creativity and wit. Menzel created the role of Maureen Johnson in “Rent” and is perhaps best  known for her role as Elphaba in “Wicked,” as well as her television work on the TV show “Glee.”
